/* Visible keyboard focus for the Filters drawer opener and close control - 2026-09-29
 *
 * Electron removes focus outlines (style-main.css: "a:focus, .btn:focus,
 * .button:focus { outline: none }"), so these two controls, now reachable by
 * keyboard through js/pco-electron-filter-a11y.js, showed no focus at all. The
 * #pcf bridge draws a 3px ring on :focus-visible for its own controls
 * (pcf-bridge.css); these two get the same one.
 *
 * :focus-visible matches keyboard focus only, so a tap or a click looks exactly
 * as before. [data-pco-a11y] is set by the script, so nothing here applies on a
 * page where the script did not run. No !important: the selectors outrank the
 * theme's generic outline resets.
